PolyPhil Hair Treatment Explained
01What PolyPhil Hair Is, and What It Is Not
PolyPhil Hair is a course of polynucleotide micro injections into the scalp. Polynucleotides are purified DNA fragments that stimulate fibroblast activity, support collagen production and encourage the formation of new blood vessels, which is the same mechanism behind our polynucleotide skin treatments.
It is worth being clear about what it is not:
- It is not a hair transplant and it does not move or add follicles.
- It is not a topical product you apply at home, although your aftercare may include one.
- It is not a single session treatment, and a single session is not how it is designed to be judged.
- It is not a replacement for a medical diagnosis if there is an underlying cause for your hair loss.
02Why the Scalp Is Treated Rather Than the Hair
Hair grows out of skin. The follicle sits within the dermis and depends on the condition of that tissue and on the blood supply reaching it. When the scalp environment deteriorates, hair quality tends to follow.
Treating the scalp directly is therefore the point of PolyPhil Hair. The injections are placed across the area of concern so the product is distributed through the tissue rather than concentrated in one spot, using the same micro injection principles we apply to delicate areas of the face.
03The Eight Session Protocol In Full
PolyPhil Hair is delivered as eight sessions in two phases:
- Phase one, four sessions. Spaced one to two weeks apart.
- Phase two, four sessions. Spaced three to four weeks apart.
The closer spacing at the start builds the treatment up, and the wider spacing that follows maintains it while the scalp responds. Eight sessions is the full protocol. A course of four is available where Dr Harry considers it appropriate, and he will explain at consultation which he recommends for you and why.
Regenerative treatments are assessed over a course rather than after a single visit, so progress is reviewed as you go.
04Who PolyPhil Hair Is Considered For
PolyPhil Hair is considered for men and women who have noticed:
- Gradual thinning, particularly at the parting or the crown.
- An increase in shedding compared with what is normal for them.
- Hair that feels finer or less dense than it used to.
- Increased shedding after starting a weight loss injection, which is a common reason people ask about this treatment.
Hair loss has many causes, and several of them are medical rather than aesthetic. Thyroid disease, iron deficiency, recent illness, rapid weight loss, medication and inherited pattern hair loss all present differently and are managed differently. Part of the consultation is establishing whether something else needs investigating first, and Dr Harry will tell you if he thinks you should see your GP before starting a course.
05Shedding After Weight Loss Injections
People starting weight loss injections often report hair shedding some months in. It is one of the most common reasons patients now ask us about scalp treatment.
What we will discuss at your consultation is the timing of your shedding against the timing of your weight loss, what your nutrition looks like now, and whether the pattern you have is one that PolyPhil Hair is a sensible option for. That conversation matters more than the treatment itself, because shedding related to rapid weight change behaves differently from inherited pattern hair loss, and for some people the right answer will be to address the cause first.
06What a Session Involves, and Downtime
A session is an appointment at either clinic in which polynucleotides are placed across the scalp through a series of micro injections. Sessions are comparable in length to a skin booster appointment.
You should expect the scalp to feel tender for a short period afterwards, and small injection points may be visible for a time. As with any injectable treatment, bruising, swelling, tenderness and, rarely, infection are possible. Dr Harry will take you through the risks that apply to you at consultation, and you will be given aftercare instructions for washing, styling and heat.
Every treatment at Dr Harry Clinic includes a complimentary review appointment within three weeks.
07PolyPhil Hair Prices
PolyPhil Hair is priced as follows at both clinics:
- Single session, £350.
- Course of four sessions, £1,150.
- Course of eight sessions, £2,200. This is the full protocol.
The course of four and the course of eight each include a complimentary Obagi Nu-Cil Biostim scalp serum, worth £135.
A consultation is £75 and is redeemable against the cost of your treatment if you go ahead. It is refundable if you decide not to proceed, and non refundable only if you cancel within 24 hours or do not attend. Full pricing for the clinic is on our prices page.
08How PolyPhil Hair Sits Alongside Other Treatments
PolyPhil Hair treats the scalp, so it does not compete with the facial treatments many of our patients already have. The complimentary Obagi Nu-Cil Biostim scalp serum included with the courses is intended to support the treatment between sessions rather than to replace it.
If you are already having polynucleotides, Profhilo or other collagen stimulating treatments with us, tell us at consultation so your appointments can be planned together rather than scheduled against each other.
